looking at the problem here, not only some people got their MIC totally not working.

but some other people also got their MIC partly working (the MIC turned off sometimes and needed restart to correct it)

This is a very obvious manufacturing defect IMO. you don't need to wait for weeks for it to happens like lens scratch in N97,

If you claim you test your product before you ship them (Nokia) i hope you can explain this to the public.

so how many people actually experiencing this problem?
